WINDMILL.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed September 17, 1910. Serial No. 582,503.

To all whom it may concern:

Be it known that I, JAMES R. SAwYnRs, a citizen of the United States,residing at Dexter, in the county of Dallas, State of Iowa have inventedcertain new and useful Improvements in WVindmills; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to wind mills.

The object of the invention resides in an improved construction in adevice of this character for shifting the wind wheel thereof away fromthe wind by moving said wheel from its normal vertical position to asubstantially horizontal position; said movement of the wind wheelserving at the same time to disconnect same from the drive shaftjournaled in the turn table of the mill.

WVith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views: and in which Figure 1 is aplan view of a wind mill construoted in accordance with the invention;Fig. 2, a side elevation of the upper end of a wind mill constructed inaccordance with the invention; the wind wheel thereof being shown invertical or normal position; Fig. 3, a view similar to Fig. 2 with thewind wheel thereof disposed in horizontal position and disconnected fromthe shaft carried by the turn table of the mill; Fig. 1, a verticallongitudinal section of what is shown in Fig. 3; Fig. 5, a verticallongitudinal section of the turn table of the mill on an enlarged scale;and Fig. 6, an enlarged detail view of the detachable connection betweenthe wind wheel and the shaft carried by the turn table.

Referring to the drawings A indicates the tower of the mill whichcarries at its top a turn table B. This turn table is formed of a fixedsection 10 and a movable section 11, the latter being secured againstvertical and lateral movement with the respect to the sec tion 10 bymeans of keepers 12 which are secured to the section 10 and have theirupper ends overlying a flange 13 on the inner face of the section 11.Balls 14. are disposed between the sections 10 and 11 to form africtionless bearing for the rotating member of the turn table.Journaled in the rotatable member 11 of the turn table is a shaft 15which is provided intermediately with a crank 16 to which is adapted tobe secured the upper end of the usual pump rod. One end of the shaft 15is extended through the member 11 and is provided with a tongue 17 whichconstitutes one member of the clutch connection for a purpose that willpresently appear. Fixed to the member 11 and extending laterallytherefrom in the same dircction as the extended end of the shaft 15 isan arm 17 Pivoted to the free end of the arm 17 is a bearing 18; saidbearing being adapted for movement on its pivot from a substantiallyhorizontal position as shown in Fig. 2 to a substantially verticalposition as shown in Fig. l. Journaled in this bearing and movablelongitudinally thereof is a shaft 19 one end of which carries the usualwind wheel 20 while the other end is provided with a recess 21 adaptedto receive the tongue 17 on the extended end of the shaft 15 so as tooperatively connect said shaft 15 with the wind wheel 20.

lVhen the bearing 18 is disposed in a horizontal position as shown inFig. 2 the shaft 19 is automatically moved toward the shaft 15 throughthe instrumentality of the following structure. A flange 22 is formed onthe shaft 19 at the inner end of the recess 21 and a spring 23 encirclessaid shaft with one end bearing against the flange 22 and the other endbearing against the bearing 18. The tension of this spring 23 will, asis apparent, move the shaft 19 so that the tongue 17 of the shaft 15will be disposed in the recess 21 whereby the rotation of the wind wheel20 will produce a coresponding rotation of the shaft 15 and operate thewind mill. The bearing 18 is provided against the wind wheel 20 withoppositely extending arms 24 and 25 provided at their free ends witheyes 26 and 27 respectively. Mounted on the lower side of the bearing 18adjacent to spring 23 is an eye bolt 28 in which is adapted to travel anextension 29 of the flange 22. A flexible connection 80 has one endsecured to the extension 29 and is carried through the eyes 27 and 26and over a pulley 31 mounted on the arm 17 to a point at the base of thewind mill tower so as to be within convenient reach of an operator. Thisconnection 30 is utilized When it is desired to move the Wind wheel fromthe posit-ion shown in Fig. 2 to the positions shown in Figs. 3 and 4:.hen a pull is xerted on the connection 30 by the operator it will firstserve to move the shaft 19 longitudinally against the influence of thespring 23. This movement of the shaft 19 will disconnect the latter fromthe shaft 15 and when this disconnection takes place the pull on theconnection 30 will cause the bearing 18 to swing on its pivot from ahorizontal to a vertical posi tion and will in turn cause the wind wheel20 to move from a vertical to a horizontal position. .i

From the foregoing description it Will be I apparent that the device isof an extremely simple and inexpensive construction and especiallyadapted for the purposes for which it is intended, since it is strongand durable and not liable to become deranged or broken while in use.

That is claimed is 1. In a wind mill, the combination of a turn table, ashaft journaled in said turntable provided with a clutch connection atthe bearing, a wind wheel mounted on the other end of the shaftjournaled in the pivoted bearing, a flange on said shaft adjacent theclutch connection, a spring surrounding the shaft having one end inengagement With the flange and the other end in engagement with thepivoted bearing for against the influence of said spring to dis.

engage said clutch connections.

.2. In a windmill, the combination of a turn table, a shaft ournaled 1nsaid turntable provided with a clutch connection at! one end, an armfixed on said turn table and projecting laterally therefrom, a bearingpivoted to the free end of said arm for movement in a vertical plane, ashaft journaled in said bearing and movable longitudinally thereof, saidshaft having a clutch connection on one end and being adapted to bedisposed in alinement with the shaft journaled in the turntable in oneposition of the bearing, a wind wheel mounted on the other end of theshaft journaled in the pivoted bearing, a flange on the shaft adjacentthe clutch connection, a spring surrounding the shaft having one end inengagement with the flange and the other end in engagement with thepivoted bearing for shifting said shaft longitudinally to move theclutch con nection thereof into operative engagement with the clutchconnection on the shaft journaled in the turntable, an eye fixed to saidbearing,,an extension on said flange extending through the eye,oppositely disposed extensions on said bearing having loops at each endand a flexible connection having one end secured to the extension onflange and passing through the eyes in the oppositely disposedextensions on the bearlng.

In testimony whereof, I affix my signature, in presence of twowitnesses.
